In Metrica Province, there is a skill challenge in which you have to defeat a Hylek chieftain named Utcua. In the server I’m on (Dragonbrand,) Utcua is dead. I’ve attached a picture of what it looks like. It is also impossible to select Utcua, and he has been like this for at least a day now.
From another thread:
Update update read all about it!
We’ve finally tracked down the root cause of these missing skill point NPCs and fixed it. This magical fix will be in the next patch after it goes through further testing. This fix will also address issues with missing Event NPCs, too.
We apologize for the hassle these have been, but thank you all for hanging in there while we got this issue sorted out.

As you can see, it wasn’t just an issue with the skill challenge itself, but an underlying issue that was affecting almost all skill challenges and even some events.
Thanks for your patience, everyone! We’re aware of this issue and are working towards a fix.
Utcua the Griefing Frog will be fixed in the upcoming Halloween build, which will also include a boat load of other bug fixes on top of the fun new content
